RT 2.0.4 and Postgres

I have a question:

I installed rt-2.0.4 with Postgres 7.0.3.
RT wokred fine. After instalation i made import
from RT-1.0 by tool import-1.0-to-2.0. We have about 1350 requests with
many records.

And now when i create new request i wait for displaying of form very
long time. Before import the time was very shorter.

OS … Linux Mandrake 8.0
apache … 1.3.19
perl … 5.600
postgres … 7.0.3

Can somebody help me
